The emphasis placed on unbiased reasoning processes has led researchers to highlight the importance of decontextualized reasoning.  For example (Stanovich & Stanovich, 2010, p. 196): Kelley (1990) argues that “the ability to step back from our train of thought . . . . is a virtue because it is the only way to check the results of our thinking...

Medin, L. Skitka, C. W. Bauman, D. Bartels, eds., 2009) on SSRN.  Here’s the abstract. * * * Could a computer be programmed to make moral judgments about cases of intentional harm and unreasonable risk that match those judgments people already make intuitively? If the human moral sense is an unconscious computational mechanism of some sort, as many cognitive scientists have suggested, then the answer should be yes. So too if the search for reflective equilibrium is a sound enterprise, since achieving this state of...

As a result, we often use "rules of thumb," or heuristics, to help us. These heuristics allow us to have an idea about how to weigh our options, even though they might sometimes lead us astray. Likewise, sometimes the way our options are worded, or "framed," may lead us to think differently than we might otherwise. Finally, we often allow prior experience or outcomes to guide our approach to a decision, eve...

The excerpt discusses a case of missed diagnosis of cardiac disease in a healthy man and gives a great example of the representativeness heuristic in clinical decision-making.Groopman notes of the case and how it illustrates this kind of bias:The mistake Croskerry made is called a representativeness error: yourthinking is guided by a prototype, so you fail to consider possibilities thatcontradict the prototype and thus attribute the symptoms to the wrongcause.

Here’s what Gerd Gigerenzer, a German social psychologist and the Director of the Max Planck Institute for Human Development in Berlin, has to say about gut thinking in the August 28th New York Times: It’s a judgment that is fast. It comes quickly into a person’s consciousness. The person doesn’t know why they have this feeling. Yet, this is s...
